[Radiance-general] Deterministic calculations with Radiance

[Greg Ward]

Yes, but what's the point?  A change in the compiler or a minor 
alteration of the code that makes no difference to the results but 
affects the order in which rays are traced will completely defeat such 
a test.  How can we do regression testing with something that unstable?
